That's awesome! The bottom line is that it's a good, solid product. I converted from Blackberry to an iPhone a little over a year ago. Never been happier with a purchase (I have the 3GS). My decision to pre-order the iPhone 4 was based solely on my solid experience with my iPhone 3GS. It has been a lasting, durable product that worked from the minute I turned it on and has never stopped. It's my contact book, my ToDo list, my calendar, my gaming device, my sketch pad, my journal, my everything! Oh, yeah, it's also a great phone that I use a lot for work. To have a single device that can do all so beautifully is a technological wonder.
Apple doesn't always do something FIRST, but what they do is take what others are doing and make it better. That fact that my 99 year-old grandmother was able to look at a picture on my iPhone and figure out quickly how to "swipe" from picture to picture says something about the intuitiveness of the device and its OS.
I don't tend to be a person of excess and I'm rarely the kind of person who will stand in line for something new, but I will do it for an iPhone!
